Hi gothic. I use this one: https://liftmode.com/health-promoting/a ... lfate.html. It helps the circulary system to work properly and I feel much better since I started using it. But I think there are a lot of different products for this purpose, so you might want to tell me: Do you want to use it for better health, for more focus or more energy? I tested a lot of different supplements, so I might give you some advice...
